Unlike some railroads, the station call signs on the NYC were supposed to have some relevance to the site location. Usually, this was one or two letters from the town name or for some well-known landmark.

Some of these are tricky. BN Tower stood for Bronx; NK on the Park Ave. Viaduct was for the first and last letters of New York; MO was Mott Haven Jct.

The towers / interlockings at GCT were A, B, C, F, and U as of the time I worked there. F was remoted from C; the others were attended.

Memo to SHL, I had always thought that when they did away with the person at F, the interlockings were remoted from A for the upper level and B for the lower level.

Hi, Noel:

I'm not sure that "F" ever controlled either of the Lower Level Loops.

What I do recall is the small panel that controlled the Upper Level Loop. Since "C" was not manned 24/7, there may have been a second panel at "A" for use when "C" was closed.
